Use Pythagorean Theorem:

[tex]a^2+b^2=c^2[/tex]

Plug in a=18 and b=6

[tex]18^2+6^2=c^2[/tex]

Simplify

[tex]360=c^2[/tex]

Thus when you square root both sides, you will get:

(08.05 MC)The following box plot shows the number of books sold each day at a bookstore for 40 days. How many days did the bookstore sell 2 to 12 books?

Answers

Answer:

20 days

Step-by-step explanation:

Number of books sold each day for 40 days :

The first quartile (Q1) = 2

For the 25% of the days = 2 books were sold

Hence 0.25 * 40 = 10 days, 2 books or less were sold

The upper quartile (Q3) = 12 books

For up to 75% of the days = 0.75 * 40 = 30 days ; 12 books or less were sold

To obtain the number of books sold between 2 and 12 ; we subtract :

(30 days - 10 days) = 20 days

Find all the real zeros of the function
f(x) = 2x3 - 19x2 + 38x + 24 given that x-4 is a factor.

Answers

Answer:

Zeroes: x=4, x=-1/2, and x=6

Step-by-step explanation:

Use Synthetic Division where x-4=0 to find another factor:

4 | 2 -19 +38 +24

  ___8_-44_-24

    2 -11  -6  |   0

So far, your two factors are x-4 and 2x^2-11x-6.

We can actually factor 2x^2-11x-6 into (2x+1)(x-6), so we have three factors which are (x-4), (2x+1), and (x-6)!

By the Zero Product Property, x=4, x=-1/2, and x=6 are your zeroes.

Answer:

Hope this helps!! (x,y)=(6,-5)

Answer:

y=-5

Step-by-step explanation:

substitute y=4x -29 into the equation x+y=1.

x+ 4x-29 = 1

combine like terms

5x-29=1

add 29 to both sides

5x=30

divide by 5

x=6

plug 6 into x in the original equation

y=4(6) - 29

y=24-29

y= -5
